Tangy Onion Relish: A Taste of Walla Walla Sunshine

My grandmother, a woman who believed everything tasted better with a generous dollop of homemade relish, always had a jar of something bubbling away on her stovetop. While she had many variations, her tangy onion relish, bursting with the sweetness of Walla Walla onions, was a constant. The aroma alone, a sweet and savory dance of caramelized onions, vinegar, and spice, instantly transports me back to her sun-drenched kitchen, filled with warmth, love, and the promise of a delicious meal. This recipe, adapted from a cherished community cookbook, aims to capture that same nostalgic flavor, bringing a touch of sunshine to your own table.

Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 20 minutes
• Total Time: 3 hours 40 minutes (includes refrigeration time)
• Yields: 3 cups
• Dietary Type: Vegetarian, Gluten-Free

Ingredients

• 6 medium Walla Walla onions, peeled and diced
• 1 medium red bell pepper, seeded and diced
• 1/2 cup brown sugar, packed
• 1/2 cup apple juice
• 1/3 cup cider vinegar
• 1 tablespoon salt
• 1 tablespoon prepared horseradish
• 1 tablespoon canola oil (or olive oil)
• 2 1/2 teaspoons prepared mustard

Equipment Needed

• 3-quart, non-aluminum saucepan
• Mixing bowl
• Spoon
• Covered container

Instructions

1. In a 3-quart, non-aluminum saucepan, combine all ingredients: the 6 medium diced Walla Walla onions, 1 medium diced red bell pepper, 1/2 cup packed brown sugar, 1/2 cup apple juice, 1/3 cup cider vinegar, 1 tablespoon salt, 1 tablespoon prepared horseradish, 1 tablespoon canola oil (or olive oil), and 2 1/2 teaspoons prepared mustard.
2. Place the saucepan over medium heat and bring the mixture to a boil, stirring occasionally to prevent sticking. Make sure that the brown sugar is dissolving evenly into the liquids.
3. Once boiling, reduce the heat to low. It’s important to use low heat to prevent burning of the mixture as it simmers.
4. Simmer the relish uncovered for 20 minutes, stirring occasionally to make sure the relish is cooking evenly. This allows the flavors to meld and the onions to soften. The mixture will thicken slightly.
5. Carefully spoon the hot relish into a mixing bowl. Be careful, as the mixture will be hot.
6. Cover the bowl and refrigerate for approximately 3 hours. This allows the relish to cool completely and the flavors to fully develop.
7. Transfer the chilled relish to a covered container. Store unused relish in the refrigerator for up to 2 weeks.

Expert Tips & Tricks

• Onion Prep: Dicing the onions uniformly is key for even cooking. If you’re sensitive to onion fumes, try chilling the onions in the freezer for 15 minutes before dicing.
• Non-Aluminum Pan: Using a non-aluminum saucepan is crucial because the acidity of the vinegar can react with aluminum, creating a metallic taste and potentially discoloring the relish. Stainless steel or enamel-coated cast iron are good alternatives.
• Simmering Patience: Don’t rush the simmering process. The 20 minutes of simmering is essential for softening the onions and allowing the flavors to meld together. Stirring occasionally prevents sticking and ensures even cooking.
• Flavor Boost: For a deeper, richer flavor, try adding a pinch of smoked paprika during the simmering process.
• Sweetness Adjustment: If you prefer a less sweet relish, reduce the amount of brown sugar by a tablespoon or two. Alternatively, you can add a tablespoon of balsamic vinegar for a more complex tang.
• Heat Level: If you like a little more kick, you can add a pinch of red pepper flakes or a finely minced jalapeño pepper during the simmering process.

Serving & Storage Suggestions

This tangy onion relish is incredibly versatile. It’s a fantastic topping for grilled burgers, hot dogs, sausages, steak, and chicken. It also adds a delightful zing to sandwiches, wraps, and even tacos. Serve it alongside roasted vegetables or grilled halloumi for a flavorful vegetarian option.

Store any leftover relish in an airtight container in the refrigerator. Properly stored, it will keep for up to 2 weeks. The relish is best served chilled, as the flavors deepen and become more pronounced after refrigeration. While you could freeze the relish, the texture of the onions may change slightly upon thawing, becoming a bit softer.
